Description:

FIELD

The embodiments of the present invention relate generally to a fall prevention apparatus that helps prevent workers and equipment from falling from structures such as buildings. More particularly, the present application involves a fall protection assembly that may have a base member and an upright support member capable of supporting cross members for use in retaining workers and equipment.

BACKGROUND

During the construction and maintenance of structures, workers are placed at risk of falling from heights that can result in injury or death. Additionally, tools and other equipment may also fall from the structure resulting in their destruction or in the injury of other workers or bystanders on the ground below. In view of these dangers, insurance companies and government agencies have mandated that a safety barrier be constructed on a roof to prevent accidental falls.

A typical roof safety barrier includes a base that is mounted via nails or other fasteners to a roof or framing member of the structure. A post extends from the base and carries a number of cross members. Additional base and post assemblies are arranged along the perimeter of the roof. The cross members, which are pieces of lumber that are cut to size, extend the distance between adjacent posts and function as a barrier to prevent workers from falling off of the roof. A row of cross members can be located proximate to the upper end of the posts and additional rows may be included along the length of the posts. Kick members, which are also pieces of lumber, can extend between the posts and may be positioned at their bottom near the surface of the roof in order to prevent tools and equipment from sliding off.

While some roof safety barriers employ lumber as cross members, others may instead employ cable. In this regard, loops are attached to the posts through which the cable is disposed. A turnbuckle is provided at some point along the length of the roof safety barrier in order to take up slack in the cable to achieve a desired tightness necessary in providing resistance to falling. The use of a turnbuckle may be problematic in that during tightening of the cable forces may act on one or more of the posts and bases causing them to shift positions or possibly even detached from the roof.

Although suitable for their intended purpose, roof safety barriers are sometimes provided with bases that are rigidly attached to the posts. This arrangement may be heavy and awkward to maneuver thus necessitating two workers position and balance the rigidly attached base and post at the end of the roof during installation. Further, bases of roof safety barriers may be provided with a plate that is configured for attachment to the vertical face of the structure to which the roof safety barrier is installed. The face plate may be of such a size that it damages the surface of the building to which it is attached. Additionally, in other arrangements the plate may not be attached to the vertical face of the building but may still cause damage thereto. For example, wind or other forces may cause the plate to rub against the building thus resulting in damage and discoloration. As such, there remains room for variation and improvement within the art.

An embodiment of the present invention provides for a fall protection assembly 10 that can be used to provide safety to workers who work at dangerous heights at a site under construction or maintenance. The fall protection assembly 10 may help prevent a worker from falling from a roof of a building or other structure.

Referring to FIG. 1, a fall protection assembly 10 is shown installed at a horizontal surface of a structure for preventing workers from falling from the surface which can be situated at a dangerous height. According to a first embodiment, the fall protection assembly 10 is installed at the edge 12 of the horizontal surface 14 of the structure. For the purpose of description, the element “member”, as used hereinafter, shall be understood to be possibly manufactured from any material, for example steel and the like, suitable for construction of such an element. The fall protection assembly 10 has a plurality of post-base assemblies 100. Each post-base assembly 100 has a base member 16, an upright fitting 26 and an upright support member 18. The upright fitting 26 can be fixedly attached by means of welding, riveting or the like to the base member 16 to form a base-plate assembly 56 as shown in FIG. 2 (also in FIG. 3(a)). However, it is to be understood that in accordance with other embodiments that the base-plate assembly 56 need not include the upright fitting 26.

The base member 16 can be used to removably mount a plurality of upright support members 18 about the perimeter of the horizontal surface 14 at spaced intervals. The upright support members 18 are used for supporting cross members 20 and 22. The cross members 20 and 22 serve as safety rails to prevent the workers from falling from the horizontal surface 14. The cross members 20 and 22 illustrated in FIG. 1 are made of cables. However, it is to be understood that in accordance with other embodiments that the cross members 20 and 22 can also be rigid horizontal members or a combination of cables and rigid horizontal members. The length of the cables used as the cross members 20 and 22 may be eight feet.

Apart from the cross members 20 and 22, one or a plurality of elongated members 24(b) span the distance between two adjacent base members 16. The two ends of the elongated member 24(b) can be removably fixed to the two adjacent base members 16. The elongated member 24(b) can be a rigid horizontal kick member. In this regard, the kick member can be used to prevent tools or other objects from sliding off of the roof. The kick member may also be capable of at least partially preventing workers from falling off of the roof as well. At the top of each upright support member 18 an attachment member 30 can be located.

Each upright support member 18 also carries a bolt 58(a) and a bolt 58(b) which can be attached to shackles 60(a) and 60(b), respectively, for supporting the cables that are used as the cross members 20 and 22. Between the adjacent upright support members 18, for which the rigid horizontal members are being used as the cross members 20 and 22, it is optional to install the warning flag string 32. The warning flag string 32 may be retained using the attachment member 30 provided on the top of each upright support member 18 as shown in FIG. 7. In a similar manner, when cables are being used as the cross members 20 and 22 the warning flag string 32 can be incorporated using the attachment member 30 provided on the top of each upright support member 18, shown for example in FIG. 7. The second plate 16(b) of the base member 16 may be sized 2 inches in order to avoid damage to the surface to which it is tied.

All of the embodiments of the fall protection assembly 10 may be designed to meet current OSHA regulations and can be installed at any structure with ease and convenience. The first step in the installation procedure is to secure the base member 16 at the outside edge of the structure, for example at the roof-edge of a building. The first plate 16(a) may be pulled tight to the horizontal surface 14 of the roof-edge and the second plate 16(b) may fit flush against the vertical surface of the roof-edge as shown for instance in FIG. 3(a). The first plate 16(a) can be fastened to the horizontal surface 14 of the roof-edge with a minimum of 6 fasteners in such a way that there are an equal number of fasteners on each side of the upright fitting 26. Each of the fasteners may be at least 1.5 inches in length for suitable securement. The fastener to be used should be designed from a material that allows the fastener to work in the material to which it is fastened. The base member 16 can be tightly secured to the roof by using fasteners passing through the holes 44 provided on the first plate 16(a) to avoid the need for a person to bend over the roof and secure the second plate 16(b) to the vertical surface 15. However, for additional attachment, the second plate 16(b) may be fastened to the vertical surface 15 of the roof-edge using fasteners passing through the holes 42 provided on the second plate 16(b). In accordance with other embodiments, the second plate 16(b) may be attached while the first plate 16(a) is unattached to the roof-edge.

The next step in the installation procedure is to insert the upright support member 18 in the upright fitting 26. The upright support member 18 should be installed so that that the side of the upright support member 18 carrying the links for supporting the cross members 20 and 22 is facing inward towards the roof. A desired height of the upright support member 18 is selected by aligning the first set of apertures 34 present on the upright fitting 26 with the second set of apertures 34′ present on the upright support member 18. The aligned apertures 34 and 34′ are fastened with the snap pin fastener 28. The selected height of the upright support member 18 should be at least 40 inches to meet government regulations in accordance with certain exemplary embodiments.

Once the upright support member 18 is installed, an end of the elongated member 24(b) is inserted in slot 50(b) of the base member 16. The other end of the elongated member 24(b) locates the position for slot 50(a) of a subsequent base member 16 which will be installed. After the two ends of the elongated member 24(b) are inserted into their respective slots they are secured with the help of fasteners. In accordance with one embodiment, the elongated members 24(a) and 24(b) are eight feet long, 2 inch by 4 inch (2×4 inches) boards. By using the elongated members 24(a) and 24(b) as spacers, the need for use of a measuring tape is eliminated. The distance between the adjacent base members 16 should not be more than six feet in accordance with certain embodiments.

Next, the cross members 20 and 22 can be installed between adjacent upright support members 18. In the embodiment shown in FIG. 1, the cross member 20 is formed by attaching the shackle 60(a) to one end of a cable and to bolt 58(a), while the other end of the cable is attached to another shackle 60(a) that is attached to another bolt 58(a) of the subsequent upright support member 18. A similar procedure is performed for forming the cross member 22 in which the shackle 60(b), attached to one end of a cable, is attached to the bolt 58(b), while the other end of the cable is attached to another shackle 60(b), that is attached to another bolt 58(b) of the subsequent upright support member 18. The length of the cable which serves as the cross member 20 or 22 should be equal to the distance between the adjacent upright support members 18 so as not to create any slack in the cable after it is installed. If the distance between the adjacent base members 16 is less than eight feet, the rigid horizontal members can be used to form the cross members 20 and 22.

In the embodiment shown in FIG. 4, rigid horizontal members are placed in the support brackets 36(a) and 36(b) in order to form the cross members 20 and 22. Cross member 20 is further secured with the bolts 38(a) and 40(a), and cross member 22 is further secured with the bolts 38(b) and 40(b). The final step in the installation process is to install the warning flag string 32 so that the warning flag string 32 passes through each attachment member 30 provided at the top of each upright support member 18. The warning flag string 32 may not be installed between the upright support members 18 that have rigid horizontal members as the cross members 20 and 22.

It is therefore the case that a plurality of post-base assemblies 100 may be installed around the roof for fall prevention and protection with proper installation and use. The fall of personnel from the surface may be prevented by the cross member 20, the cross member 22 and the elongated members 24(a) or 24(b). The elongated members 24(a) and 24(b) can also be used to prevent any tool or object from falling from the surface 14 and thus getting damaged or hitting a person standing directly below the edge of the surface 14.

As stated, the upright support member 18 may be independent from the base member 16. A base member 16 may be fabricated to accommodate a flat roof or any steep pitch. This flexibility allows the end user the option of buying special steep slope base plates and using their existing safety posts for the rest of the fall protection assembly 10. However, it is to be understood that in other embodiments that the base plate assembly 56 and the upright support member 18 may be permanently attached to one another.

The base member 16 has been described as being attached to a structure. The structure may be any component of a roof or wall of a building. Further, the structure may be a 2×4 or other board or member located on any part of a building. Still further, the structure to which the base member 16 may be attached can be various components in accordance with other embodiments.

While embodiments of the present invention have been described, it is to be understood that the claimed invention is not to be limited in scope to the aforementioned and described embodiments.
